Unable to restart Uyuni following Uyuni upgrade 2021-06

24 Jun 2021

      Hi Folk,

Thanks for the new release - but I'm having significant issues (around four hours so far) in updating this and currently have a broken system.

Please advise!

'spacewalk-server status' reports all is fine, however the webui times out (At other stages, it was returning a 404 for all urls)

Steps I have done:

  *   Changed repos and upgraded base OS to Leap 15.3
  *   Upgraded database as per https://www.uyuni-project.org/uyuni-docs/en/uyuni/upgrade/db-migration-13.ht...
  *   Changed the Uyuni repo.
  *   Normal Uyuni upgrade.

All package issues seemingly resolved, apart from this:

Problem: the to be installed patch:SUSE-2020-3767-1.noarch conflicts with 'apache-commons-el < 1.0-3.3.1' provided by the installed apache-commons-el-1.0-bp153.2.24.noarch
Solution 1: Following actions will be done:
  deinstallation of apache-commons-el-1.0-bp153.2.24.noarch
  deinstallation of spacewalk-java-4.2.23-1.7.uyuni1.noarch
  deinstallation of spacewalk-common-4.2.3-1.6.uyuni1.noarch
  deinstallation of spacewalk-postgresql-4.2.3-1.6.uyuni1.noarch
  deinstallation of patterns-uyuni_server-2021.06-2.3.uyuni1.x86_64
  deinstallation of susemanager-4.2.19-1.2.uyuni1.x86_64
  deinstallation of supportutils-plugin-susemanager-4.2.2-2.4.uyuni1.noarch
  deinstallation of uyuni-cluster-provider-caasp-4.2.3-1.4.uyuni1.noarch
Solution 2: do not install patch:SUSE-2020-3767-1.noarch

(Did try #1, then reinstalling uyuni-server patterns, but it just reappears. ISTR there was a breaking issue with apache-commons-el in a previous update)

The main issue appears to be related to this, in catalina's logs: (The dir is present and has an index.jsp file and dirs.)
